The genus Elaeidobius Kuschel, 1952 (Curculionidae, Curculioniae, Derelomini) is an Afrotropical associated with the male inflorescences of oil palm Elaeis guineensis Jacq. activity species in this critical for pollen transportation and fruit set economically important palm. In study, was revised using integrative taxonomic approach, combining traditional treatment analysis sequences mitochondrial genes (COI COII). A total eight now recognized: five formally included within it [E. bilineatus...
Palm oil is nowadays the first vegetable consumed worldwide. Given world population growth and increasing demand in fat for food fuel, increase palm production expected to continue. It thus important find ways of reducing ecological impact plantations at both agroecosystem mill supply area levels, by improving agricultural practices land uses. This where agroecology can play a very critical role. The present article gathers short stories on agroecological currently taking place South-East...
The pollination of two oil palm species, Elaeis guineensis Jacquin and oleifera Cortés (Arecales: Arecaceae), depends on a mutualistic relation with insects, which use male inflorescences as brood site, visits female lured by the emitted odor, is similar to that males. Although activity visiting these insects critical for adequate natural host plant, their poorly documented. In present study, we determine diel specialized pollinator weevils (Coleoptera: Curculionidae) respective host-palm:...
Abstract In recent years, the coconut whitefly, Aleurotrachelus atratus Hempel, has been recorded from various islands in southwestern Indian Ocean. Field surveys La Réunion, Seychelles, Comoros and glasshouses Paris have allowed us to record this whitefly on 56 palm species, some of which are endemic and/or threatened species. Most trees showed low infestation levels, except for that is its main host plant. Such a wide range facilitated rapid geographical dissemination whitefly. A field...

The castniid palm borer, Paysandisia archon (Burmeister) (Lepidoptera: Castniidae), is a South American moth that in the last ten years has become major pest of trees Mediterranean region. Current knowledge on reproductive behavior this diurnal suggests importance both visual and chemical cues, particular production male pheromone emitted during specific scratching behavior. Male-produced scents have diverse functions lepidopteran sexual communication but generally act courtship behavior,...
Abstract We used radiotelemetry and/or chemical light‐tags to track the flight of 15 individuals Scapanes australis in Madang Province, Papua New Guinea. This species causes severe economic impacts on coconut palms young plantations. Flights feeding, mating, resting, and possibly oviposition sites covered distances 52 835 m males, from 245 to>1000 females. Upon release, females flew a tight upward spiral above canopy level (>20 m), then usually along single bearing out radio reception...
Abstract Aim Mutualistic systems involving plants and brood pollinators show intriguing cases where a single plant is pollinated by several closely related sympatric species. This study aims at identifying the mechanisms involved in such an extreme case, 10 weevil species are only associated with African oil palm inflorescences. We assessed patterns timing of speciation this peculiar assemblage to explore main drivers its diversification. Location Tropical Africa. Taxon The Elaeis guineensis...
Abstract Elaeidobius kamerunicus Faust (Coleoptera, Curculionidae) is one of the specific pollinators on inflorescences African oil palm Elaeis guineensis Jacquin. This derelomine weevil native to tropical Africa. During late 20th century, it was introduced into all regions where E. grown, in order improve its pollination and fruit set. Despite an overall success, a decline efficiency has been documented several regions. In this study, we reconstructed multilocus phylogeography world...

Abstract The palm pest Scapanes australis has been the object of considerable recent research to develop control measures that target male reproductive behaviour. This study investigated horn size scaling relationships and frequency distributions in two subspecies S. for evidence alternative strategies. Indeed, a sigmoidal allometry both populations was detected as significant vertical discontinuity by piece‐wise regression model, which indicates distinct minor major phenotypes are expressed...
Biological control of insect pests consists the beneficial action entomophagous predators and parasitoids, entomopathogenic microorganisms (protozoa, nematodes, bacteria, fungi, viruses) in controlling pest populations. There are three biological strategies: classical control, conservation, augmentation. Because Rhynchophorus ferrugineus (red palm weevil, RPW) Paysandisia archon (palm borer moth, PBM) invasive species a large area, it could be hypothesized that only feasible suitable...

Scapanes australis is a major coconut pest, endemic in Papua New Guinea. Early the night, males placed singly into artificial galleries made young palms exhibited sex specific calling behaviour for 1 to 1.5 h. Coming gallery entrance, they raised abdomen and hind legs, head lowered inside gallery, emitted liquid secretion, rhytmically smeared by crossing legs. Females which did not behave so, were very mobile. The adult flying period coincided with male behaviour. In field assays caged...
Oryctes rhinoceros (Scarabaeidae, Dynastinae) trapping is possible with the pheromone (ethyl 4-methyloctanoate) as attractant. This article describes a new type of trap that functions without insecticides or water, and can remain in place for several months any particular maintenance so long attractant does not run out. As it 2 m tall, offers advantage having silhouette palm stem, which visually attractive to this insect
